Gar-Bro G-Series General Purpose Concrete Bucket 1/3 CY

Gar-Bro G-Series General Purpose Concrete Bucket — Heavier Duty 1/3 CY Performance for Demanding Pours

The Gar-Bro 411-G is a 1/3 cubic yard G-Series General Purpose concrete bucket engineered for contractors who need a heavier duty option when placing a wide range of concrete mixes across commercial and industrial jobsites. Designed and manufactured in the United States to meet or exceed ASME standards, this round concrete bucket has been a trusted tool in the construction industry backed by Gar-Bro's reputation dating to 1923. With a 36-inch inside diameter, a 15×18-inch gate, and a 355-pound working weight, the 411-G is built to handle demanding placements where lighter-duty buckets fall short. It is suited for crane or hoist deployment on projects requiring precise, controlled concrete discharge.

Unlike the lighter R-Series buckets intended for general contractors with less intensive demands, the G-Series is the heavier duty choice when concrete mix types, placement conditions, or pour frequency require greater structural robustness. The 411-G also supports an optional accordion hopper (Item 409-E), optional forklift pockets, and an optional 1/4 yard extension collar, making it a highly configurable tool across a broad range of project types.

Key Features & Benefits

Heavier Duty G-Series Construction

The G-Series designation signals a step up in structural integrity over lightweight alternatives, making the 411-G appropriate for contractors placing a wide range of concrete types and working in more demanding site conditions. The heavier build translates to greater longevity and reduced maintenance downtime on active jobsites. This is the go-to series when durability matters more than sheer portability.

ASME-Compliant Design

All Gar-Bro buckets are designed to meet or exceed ASME standards, giving contractors and site safety officers confidence that the equipment is built to recognized industry benchmarks. Compliance with these standards is often a project requirement on commercial and government contracts. This ensures the 411-G can be deployed without concerns about equipment qualification.

15×18-Inch Gate for Controlled Discharge

The 411-G features a 15×18-inch gate that provides contractors with reliable, controlled concrete flow during placement. Precise gate sizing reduces waste and allows operators to manage pour rates effectively, especially in confined or formed areas. An optional 22×32-inch gate is also available for applications requiring a larger discharge opening.

Optional Forklift Pockets

Forklift pockets are available as an option for all G-Series buckets, including the 411-G, providing flexibility in how the bucket is positioned and moved around the jobsite. This eliminates the need for crane-only dependency during staging and repositioning, improving site efficiency. Contractors working in environments with both crane and forklift operations will find this option particularly valuable.

Optional Extension Collar for Increased Capacity

A 1/4 yard extension collar is available for the 411-G, allowing contractors to increase pour capacity when project demands change. This modular approach means a single bucket can serve multiple capacity requirements without purchasing additional equipment. The collar option is available across all G-Series buckets for maximum fleet flexibility.

Compatible with Item 409-E Accordion Hopper

The 411-G is fully compatible with the Gar-Bro Item 409-E Accordion Hopper, which facilitates loading from ready-mix trucks and other concrete delivery equipment directly into the bucket. This compatibility streamlines the workflow between delivery and placement, reducing cycle times. The accordion hopper is an optional accessory that integrates directly with the G-Series bucket design.

Common Applications

Commercial Building Concrete Pours

The 411-G is well suited for crane-assisted concrete placement on commercial construction projects where controlled, precise pours are required in formed areas such as columns, slabs, and walls.

Industrial Facility Construction

Industrial sites requiring durable, heavy-duty equipment for repeated concrete placements benefit from the G-Series build quality and ASME-compliant design of the 411-G.

Infrastructure and Civil Projects

The bucket's robust construction makes it appropriate for infrastructure pours including bridge components, retaining walls, and other civil engineering placements requiring reliable, high-cycle operation.

Elevated or High-Rise Concrete Placement

When concrete must be placed at height via crane or hoist, the 411-G's ASME-compliant lifting bail and controlled gate operation provide the safety and reliability required for elevated work.

Foundation and Footing Pours

The 1/3 CY capacity and 15×18-inch gate make the 411-G well matched for foundation and footing pours where smaller, precise volumes of concrete need to be placed in formed sections.

General Contractor Mixed-Use Concrete Placement

General contractors working across varied project types will find the G-Series 411-G adaptable to a wide range of concrete placement tasks, from flatwork to vertical element pours, particularly when heavier duty performance is needed over lightweight alternatives.

Frequently Asked Questions

Q: What is the difference between the G-Series and the R-Series concrete buckets?
A: The G-Series, including the 411-G, is the heavier duty option designed for placing a wide range of concrete types in more demanding conditions. The R-Series is a lightweight yet robust alternative better suited for general contractors with less intensive placement requirements. Both series meet or exceed ASME standards.

Q: Can the 411-G be used with a forklift instead of a crane?
A: Optional forklift pockets are available for all G-Series buckets, including the 411-G, allowing the bucket to be positioned and moved via forklift as well as crane or hoist. Contact Gar-Bro or your DTS representative to add forklift pockets to your order.

Q: What accordion hopper is compatible with the 411-G?
A: The 411-G is compatible with the Gar-Bro Item 409-E Accordion Hopper. Note that G-Series buckets 1/2 cubic yard and larger may also use Item 409-U or 409-W hoppers; Item 409-U is not recommended for use in environments where the ambient temperature is below 50 degrees Fahrenheit.

Q: Is an extension collar available to increase the capacity of the 411-G?
A: Yes. A 1/4 yard extension collar is available as an option for the 411-G and all other G-Series buckets, allowing increased pour capacity when project requirements demand it.

Q: Is a larger gate option available for the 411-G?
A: Yes. In addition to the standard 15×18-inch gate, a 22×32-inch gate is also available. Contact Gar-Bro or your DTS representative for pricing and availability on the alternate gate size.

Q: Where is the Gar-Bro 411-G manufactured and how long has Gar-Bro been producing concrete buckets?
A: Gar-Bro concrete buckets are American engineered and American made at their facility in Heber Springs, Arkansas. Gar-Bro has been serving the construction community since 1923, bringing nearly a century of concrete bucket manufacturing experience to every product in their lineup.
